Under questioning, Costa described how he, Cerveró and other Petrobras directors had been deliberately overpaying on contracts with various companies for office construction, drilling rigs, refineries and exploration vessels. 

The contractors they were paying had formed an agreement to ensure they were guaranteed business on excessively lucrative terms if they agreed to channel a share of between 1% and 5% of every deal into secret slush funds."
